Problems solved by technology

[0009] However, in the case of silane grafting using a kneader or a Banbury mixer, silane coupling agents with unsaturated groups are generally highly volatile, and they tend to volatilize before grafting with polyolefins.
If the volatilization of the silane coupling agent cannot be suppressed, the appearance will be poor and the heat resistance will tend to deteriorate

Abstract

Provided is a production method including a step (a) in which a silane master batch is prepared by melting and mixing, at equal to or higher than the decomposition temperature of an organic peroxide (P), per 100 parts by mass of a resin composition, 0.01-0.6 parts by mass of the organic peroxide, and 10-400 parts by mass of an inorganic filler (F) including 0.1-4.0 mass% of a surface-treated inorganic filler (FT) surface treated using fatty acids and / or a phosphoric acid ester, and 0.5-18 parts by mass of an unsaturated-group-containing silane coupling agent per 100 parts by mass of the surface-treated inorganic filler. Also provided are a heat-resistant silane-cross-linkable resin composition and a heat-resistant silane-cross-linked resin moulded body which are produced using the production method; and a heat-resistant article in which the heat-resistant silane-cross-linked resin moulded body is used.
